What MINI motorists are saying about our garages

What is a car alternator?

A car alternator keeps your car's battery charged, which is obviously important because a charged battery starts your car and powers everything electrical within it. It does so using a drive belt (sometimes referred to as a serpentine belt) to convert the mechanical energy of the car's rotating crankshaft into electricity through a process of induction.

What are the possible signs of a faulty alternator?

  • Your car is difficult or slow to start.
  • Growling, whirring, whining or squealing noises are emanating from your car's engine.
  • Your car’s interior and exterior lights seem too dim, blink erratically, gradually fade, suddenly get brighter or don’t come on at all.
  • The red light on your car’s dash with the image of a battery (or the words ALT or GEN) becomes illuminated.
  • Your speedometer has stopped working.
  • You can smell rubber burning.
  • Your car fails a multimeter test at a garage.

What is the cause of a faulty car alternator?

  • The component, a brush, which maintains constant electrical contact with the spinning alternator, becomes worn.
  • The voltage regulator, which makes sure that the electrical charge is passed to the battery at the correct voltage, fails.

How long does a car alternator last?

  • On average, a car alternator can last for 8-12 years without needing for any repairs.

How much does it cost to repair a faulty alternator?

  • On average, it costs between £150-£300 to repair or replace a broken car alternator depending on the vehicle.
  • Refurbished car alternators are available but do not offer that much of a cost saving.

About Mini

A British icon since the swinging 1960s, the Mini is a small economy car that was made by the British Motor Corporation from 1959 until 2000 and is now under the umbrella of BMW. The transverse engine front-wheel drive layout influenced a generation of car makers, and allowed 80 percent of the car’s floorpan to be used for passengers and luggage - that’s a lot of space!

In 1999 the Mini was voted the second most influential car of the 20th century, behind the Ford Model T, and ahead of the Citroën DS and Volkswagen Beetle. The performance versions, the Mini Cooper and Cooper "S," were successful as rally cars, winning the Monte Carlo Rally in 1964, 1965 and 1967. The British manufacturer now offers a selection of nine cars across a broad spectrum of vehicle choices, from the traditional three door hatchback to the more radical Coupe, Countryman and Paceman. It also developed a range of frugal engines, both petrol and diesel, to reduce running costs.
